Mars Methane: A Brief Scent of Gas From a Room No One Can Open
At times, Curiosity in Gale Crater has smelled methane close to the ground. At other times, measurements show a very low background. ExoMars Trace Gas Orbiter, sent to view the wider atmosphere, has not seen the same picture. A gas trace appears, vanishes, and refuses to stay still when two instruments look from different places: this is the sort of scene in which some people see microbes breathing underground whi...
